Josie_groom89 Posted August 13, 2019 Share Posted August 13, 2019 Hi there, I've never come across a fossil like this one, it goes straight through a rock, the width being about 3.5cm. The diameter of the fossil itself is about 2/2.5cm. Found in Seaham beach, which is in the north east of the UK. So the North Sea. Any help greatly appreciated, I have a six year old who doesn't know why I dont know what it is Haha. Link to comment Share on other sites More sharing options...
grandpa Posted August 13, 2019 Share Posted August 13, 2019 Hello and welcome to the Forum to you and your six year old from Austin, Tx. I'm not sure about your fossil except that it is a very interesting and aesthetic piece worth hanging on to. I think I see 12-fold symmetry as I look at the edges. I'm hoping someone will be able to give it an ID because I'd like to know what it is as well. Neat Find! Link to comment Share on other sites More sharing options...
Josie_groom89 Posted August 13, 2019 Author Share Posted August 13, 2019 Aw thank you so much, Hi! It's pretty cool hey, I looked online at photos but I far from know the best way to search for these things. Its definitely a keeper :-) thanks for taking the time to respond Link to comment Share on other sites More sharing options...
FranzBernhard Posted August 14, 2019 Share Posted August 14, 2019 Indeed very aesthetic and strange, thanks for sharing, @Josie_groom89! Would you like to show us the back side? How thick/deep is the specimen? Is the object in question embedded in limestone or flint or something else? @TqB, @LiamL Franz Bernhard Link to comment Share on other sites More sharing options...

Josie_groom89 Posted August 14, 2019 Author Share Posted August 14, 2019 It's cool hey. Above are a few photos of the rock from different angles. I'm on my holiday at the moment, so no measuring device with me but I would say the length through the rock is about 3.5cm. I'm not amazing at rocks but it's more like flint, its very heavy for its size and no residue like some rocks gives off. Sorry this is vague, I really dont know my rocks. Someone suggested a sponge fossil... the photos were closes than anything else I've seen... any thoughts? Link to comment Share on other sites More sharing options...
Josie_groom89 Posted August 14, 2019 Author Share Posted August 14, 2019 And that's the other side 1 Link to comment Share on other sites More sharing options...
TqB Posted August 14, 2019 Share Posted August 14, 2019 Very beautiful! It's a cone from a Coal Measures (Carboniferous) plant, Calamostachys or similar from a horsetail I think - one of the plant guys might be able to narrow it down. They're well known from around there, especially in nodules like that, and always worth collecting! I can't find a TS but the structure is like this (Calamostachys), from here: https://steurh.home.xs4all.nl/engcalam/earen.html 4 Tarquin Link to comment Share on other sites More sharing options...
Rockwood Posted August 14, 2019 Share Posted August 14, 2019 Bactulite ? Took too long checking the spelling. Oh well. Link to comment Share on other sites More sharing options...

TqB Posted August 14, 2019 Share Posted August 14, 2019 Definitely one to treasure. Here's a magnified section through a Calamostachys, from this paper but behind a paywall (the image is on Google): https://www.jstor.org/stable/2440758?seq=1#page_scan_tab_contents 6 Tarquin Link to comment Share on other sites More sharing options...
